Wanting to use 4X5 reels in combination with my processor, I tested many possible configurations. It had to take as many sheets as possible and still be easy to use. After testing over a dozen design options, I determined that top-loading the sheets was the most elegant solution for ease of loading and more importantly, to make the best use of limited tank space.

The large surface of a 4x5 sheet and the geometry of the reel has a huge impact on how even development occurs across the sheet. Obviously some sort of structure is required to hold the sheet in place but this design reduces the structure to its minimum, allowing the chemicals to flow onto the film in the best possible way.
